1. If an entity currently possesses a crane, all move logic for the entity must use a MOVE WITH statement (until you free the crane)—the entity cannot move without the crane.
2. Although an entity cannot possess more than one crane at a time, the entity may possess a crane and a resource of another type.
3. If a crane is in one of the following states, another crane cannot push it away.
a) Picking up or depositing an entity.
b) Being used at a location.
c) Experiencing a downtime, off-shift time, or break time.
4. The hoist moves to its relative destination on the bridge independent of the bridge zone claim attempt outcomes. The hoist does not stop for bridge interruption so, for any particular crane move, the combined trajectory of hoist and bridge may change depending on zone availability at the time of the claim.
5. When a crane pushes away an idle crane, the idle crane comes under the control of the work and park search lists defined for the node closest to its bridge.
